To evaluate the expression \( y^2 + 4y + 3 \) when \( y = 7 \), we will substitute \( 7 \) for \( y \) in the expression.
1. Substitute \( y = 7 \) into the expression:
\[
7^2 + 4(7) + 3
\]
2. Calculate \( 7^2 \):
\[
7^2 = 49
\]
3. Calculate \( 4(7) \):
\[
4(7) = 28
\]
4. Now sum these results:
\[
49 + 28 + 3
\]
5. First, add \( 49 \) and \( 28 \):
\[
49 + 28 = 77
\]
6. Finally, add \( 3 \):
\[
77 + 3 = 80
\]
So the value of the expression \( y^2 + 4y + 3 \) when \( y = 7 \) is \( \boxed{80} \).
